SDCL1005C2N2BTDF 产品概述

一、概述

SDCL1005C2N2BTDF 为顺络(Sunlord)出品的0402(公制1005)贴片叠层电感,标称电感量 2.2 nH,直流电阻(DCR)200 mΩ,额定直流电流 300 mA,品质因数 Q = 8(@100 MHz),自谐振频率(SRF)约 6 GHz。该器件体积小、频带宽、适用于对尺寸和高频特性有要求的移动终端、射频前端及高密度混合信号电路。

二、主要技术参数

  • 电感值:2.2 nH
  • 额定电流:300 mA(连续)
  • 直流电阻(DCR):200 mΩ
  • 品质因数:Q = 8 @ 100 MHz
  • 自谐振频率:≈ 6 GHz
  • 类型:叠层(多层)贴片电感
  • 封装:0402(1005 公制)
  • 简短描述:贴片电感 200mΩ 2.2nH 8@100MHz

三、频率与电气特性分析

在低于自谐振频率的工作区间,器件表现为感性,阻抗随频率线性上升(Z ≈ jωL),适合用作射频匹配、偏置电感或串联阻抗元件。Q 值 8@100 MHz 表示在中高频段存在一定损耗,DCR 相对偏高,意味着在低频直流通流时会产生较大的 I^2R 损耗。SRF 6 GHz 提示在 GHz 级别仍可保有感性特性,但靠近 SRF 时相位与阻抗特性将发生明显变化,超过 SRF 后呈容性行为。

四、典型应用场景

  • 射频天线匹配与微调网络(低到中 GHz 频段)
  • 射频偏置(Bias-T)与电源去耦、隔离
  • 高频滤波与串联阻抗(例如 EMI 抑制、滤波器的一部分)
  • 高频放大器输入/输出匹配网络
    注意:因额定电流较低(300 mA),不建议用于大电流电源滤波或功率电感场合。

五、封装与焊接注意事项

0402 小封装要求在 PCB 走线与焊盘设计中控制焊接热量与机械应力。推荐采用标准 0402 阶梯焊盘并遵循厂商推荐回流曲线;避免过长的回流高温或多次回流导致性能漂移或焊接失效。安装时保证走线短且对称,以降低寄生电容与串扰。

六、选型与设计建议

  • 若工作频率靠近 GHz 级,需通过网络分析仪测量 S 参数以确认实际阻抗与相位行为;不要仅以标称 L 值判断工作性能。
  • 对于连续直流分量或大电流应用,应留有安全裕量(建议实际工作电流 ≤ 60%–80% 额定值),以减少温升与长期漂移风险。
  • DCR 较高时会带来额外损耗,若对损耗敏感宜考虑更低 DCR 型号或替代封装。

七、可靠性与检验建议

建议在量产前进行温升测试、回流焊耐受性测试和频率特性验证(Z、Q、SRF、S11/S21)。确认在目标工况(温度、频率、偏置)下性能稳定且满足 EMI/EMC 要求。

八、结论

SDCL1005C2N2BTDF 以其小尺寸和较高自谐振频率,适合用于对板级空间和高频响应有要求的射频与高频电路。选型时需综合考虑 DCR、额定电流与实际工作频段,通过实验验证器件在目标电路中的真实表现,以获得最佳的电气与热可靠性。

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
